The energetic utilisation of crystalline solar cell systems, in the size of domestic small power stations in 2014

Abstract

Human life is based on energy consumption, and one of the biggest challenges is that the world's demand for
energy continues to grow. The aim of present study is to review the world's energy demand and energy
supply, the determination of the degradation of solar cells, the characteristics of the Hungarian energy supply,
the introduction of renewable energy utilization and the economic determination of the return of crystalline
solar systems in Hungary.
The main direction of my recent research is the utilization of photovoltaic solar energy. The studies were
performed with crystalline solar systems. The research was carried out in solar-electric power plants
extended from 2 kWp to 16.5 kWp.
The study included the investment of crystalline solar cell systems. The calculation of payback time was
performed by static and dynamic indices.
